l. The present invention relates to a printing type lock-up structure.

More particularly, the invention relates to a printing type lock-up structure of the variety utiliz'ing two transversely disposed, relatively movable sets of parallel locking bars.

Known methods of setting printing type have heretofore required the use of what is known as a printers chase which is nothing more than a rectangular frame that has xed dimensions depending on the size printing press with which it is used, and that is designed to have the printing type to be formed mounted within it. With printing forms which are substantially equal in dimensions to the area enclosed by the chase, little trouble is experienced in mounting the type Within the chase. However, with printing forms having dimensions which are smallerY than the area enclosed by the chase, it is necessary to utilize varying numbers of different sized blocks, called printers furniturey with the printing form in order to support the form within the chase. Since considerable time andA labor are required in order to support the printing form within the chase by means of the furniture, and, since the furniture itself is relatively expensive, it is apparent that this method of locking up printing type securely is extremely costly and wasteful. In order to do away with the need for furniture when locking up printing type, a printing type lock-up structure was disclosed in my United States Letters Patent 1,525,937, issued February 10, 1925, in which two transversely disposed, relatively movable sets of parallel locking bars are used to retain a'printing form within a chase in. place of the furniture. While this form of lock-up structure is satisfactory in many respects, some difficulty has been experienced because of the manner in which the transversely disposed lock bars are secured together at their intersection.

It is therefore one object of the present invention to provide a novel printing type lock-up structure of the kind utilizing two relatively movable, transversely disposed pairs of parallel locking bars that can be used to lock up printing forms with or without substantial amounts of printers furniture, or quoins, and that greatly facilitates the locking up of printing forms.

Another object of the invention is to provide a novel printing type lock-up structure of the movable, intersecting locking bars variety wherein the rindividual bars of the lock-up device may be immediately and positively locked in a set position 13 Claims. (Cl. 101-393) relative to each other after having been properly aligned.

Still another object of the invention is to pro-v vide a novel, relatively cheap printing type lockup structure of the movable, intersecting locking bar variety which does not require the use of locking collars, or otherwise, at the intersection of thevindividual locking bars in order to maintain the locking bars in assembled relation, and therefore is capable of handling larger printing forms than would otherwise be the case if locking collars were required.

A further object of the invention is to provide a printing type lock-up structure of the movable, intersecting locking bar variety wherein stresses imparted to the locking bars by the locked up printing form is absorbed mainly by the locking bars themselves, which are interlockecl through the agency of intermeshing teeth, and does not have to be absorbed by locking collars, or the like, that are subject to mechanical failure.

A still further object of the invention is to provide a novel printing type lock-up structure which may be used with or without a printers chase, and which consequently allows much larger printing forms to be used on a particular printing press than would otherwise be the case if the lock-up device had to be mounted within a chase.

A still further object of the invention is to provide a lock-up structure which may be used to simplify the locking up of printing forms on an angle.

A still further object of the invention is to provide a lock-up structure of the movable, interseating locking bar variety having a simple safety locking latch for maintaining the bars in assembled relation.

A still further object of the invention is to provide an interlocking bar structure that may be used as a page tie-up, in place of string, or other known means used to tie up a page of type.

Still a further object of the invention is to provide a novel interlocking structure adapted for use as a galley for receiving type having removable interlocking ends.

A still further object of the invention is to provide an interlocking structure comprising an improved means for vlocking yup a foundry form of type.

A feature of the invention is the provision of a novel, interlocking bar structure, including a first .set of spaced, parallel locking bars having undulations formed on corresponding sides thereof, and a second set of spaced, parallel locking bars transversely disposed with relation to the rst set of secting bars having complementary undulated engaging surfaces which can be designed to allow for locking the bars at an angle.

Other objects, features, and many ci the attendant advantages of this invention `will: be appreciated readily as the same becomes unddteod' by reference to the following detailed description e when considered in connection with the acrierriy panying drawing, wherein similar parts in each of the several iigures, aro designated by thesame reference numeral, and whor...r.1.

In practicing, the invention, a printers lock-up structure is provided for use in locking up printn ing forms to be placed on. a printing press. The lock-up structure includes a first setof spaced, parallel locking. bars having undulations formed on corresponding sides thereof, and a second' set of spaced, parallel locking bars transversely disposed with relation Ato the nrstementioned set of bars, and having undulations formed on corresponding sides thereof. Tlie undulated sides of the second set of locking bars are adapted tol engage the undulated sides of the iirst set of locking bars, with the undulations in the second set of bars complementally meshing with the uri-- dulations in the firstv set of bars to firmly interlock the sets of bars against relative axialinoven ment. To prevent the bars from being separated by forces acting transverse to the longitudinal axes thereof, safety locking means may be provided at the intersections. And in order that the lock-up structure be capable of locking up larger printing forms on any given size printing press, additional end members are provided for use with the lock-up structure, which allow the device to be locked up on a printing press without the use of a printers chase.

Referring novv.` to Eig; 1; of` the drawings, a printing form comprising a body of set printing type is shown at I I. The printing form is locked up within a novel printing type lock-up structure which.. includes a rst set of spaced, parallel,

elongated locking bars I2, and a second set of Spdipirallel, elongated locking bars I3 transversely mounted with relation to the first set of locking bars. The two sets of transversely disposedlocking bars together denne a generally rectangular shaped area; for receiving the printing form. which may be varied. to. accommodate any desired size printing form. The, printing fjorm is looked. up in this area by Ineensy of. a pair of printers quoins. I 4 adaptedto. bginselted between the edge ofA the printing. form IVI and the l bar adjacent the particular edge in questi, then expanded to firmly lock the printing form within the lock-up device.,V The, lock-up. device with the printing forni II locked up thereinI may then be locked Within a .printers chase I6, which comprises a generally rectangular frame having tapered edges IIA by means; of; which the, chase is clamped on a printingy press.

rI'he first s et of locking bars I2' are, generally rectangular in cross section, and have undulations formed on corresponding sides thereof. As 1s best seen in Fig. 2, the undulations comprise a plurality of longitudinally extendinghrectangjular-shaped grooves IIa formed on the upper side of each of thebars,.a.11d a plurality of transversely running teeth I8 formed oneeach of' the inner and outer sides of the bar bordering upon the side containing grooves I'Ija. For a purpose hereinafter explained, the transversely extending teeth on one of the sides, namely the outermost sides when the bars are set in parallel relation in the manner shown in Fig. l, extendy only midway the thickness of the bar, and are undercut on the inner end, as at I3, to form an overhangingl lip.

The second set of lockingbars I3 are; also generally rectangular in cross section, and, have a plurality of'undulations formed in correspllioling sides thereof. The undulations in the second set of locking bars I3 are adapted to mesh withV the undulations on locking barsl I2', and as is best shown in Fig. 3, comprise Va series of aligned, separated, rectangularly shaped, pedestal-like teeth 2l 'formed on the lower sides Vofeaeh off the bars I3. Each of thebars also has a longtiudinale ly extending groove 22 formed; in that side which is outermost when the bars are set in parallel relation...

In assembling the printing ferm i I' within-the lock-up structure, one-'ef theA sets of lock-ing; bars i2 is first laid out with. the. side thereof having grooves Ila. therein facing, uptvardly-,- and one of. the sets oi lockingoars I3. is. then set. transversely to, preferably at. right arlsles.k Vthe locking bar I2Y with the face tl'iereoi having teeth 2l thereon facing downwardly. To facilitate the setting of the locking bar it` on the laid out locking bar I2, each of the locking bars I2 have a, printers scale 23 formed thereon which is used in determining the position of the transverse locking bar I3. For a particular size printing forni, the rst ofthe locking'bars 'I3 is placed on the laid out locking bar I2 at a distance of one-half of the vertical dimension of the form measured from 'the zero point of the scale. The zero point is located midway theV end of the bar With markingsl of the scale increasing ineach direction from'the zero point towards'each of the end-s of the bar. In order that the printing form be properly centered in the lock-up structure, the position of the locking bar I2 relative to the locking bar I3 may be determined by means of a similar printers scale 24 lformed on each of the locking 'bars I3. Having positioned the locking bars in proper relation to one another,

they are then pressed together so that the undulations or teeth 2l `formed on the locking bar I3 mesh with the undulations or grooves Ila and voids between transverse teeth it', in the manner shown in Fig. to securelyv interlock fs the locking bars I2 and I3 against relative axial movement ofthe two. The printingv form' II is then placed so that one of the corners thereof is complementally received by the intersection of the locking bars. Quoins Ill are placed adjacent the edges of printing form not engaged by the previously set locking bars, and each of the remaining locking bars l2 and I3 positioned adjacent each of the quoins in intersecting relation. Upon pressing the last two mentioned locking bars into interlocking engagement with the rst two mentioned locking bars, and tightening .the quoins I the printing form will be locked up in the novel lock-up structure in the manner shown in Fig. 1.

From the above description, it can be readily appreciated that the lock-up device can be used to lock a printing form' on a printing press without requiring the use of substantial amounts of Vprinters furniture, and therefore greatly facilitates the locking up of printing type on a printing press. Because of the manner in which the locking bars of the lock-up structure are interlocked, the device may be readily 4adjusted to accommodate any desired size printing form without requiring the setting or adjustment of a plurality of locking collars, or similar mechanisms, requiring time-consuming manipulation. All that is required is that the bars be aligned in a desired position, and simply pressed together. Once the locking bars are in' a set position, they are firmly interlocked against stresses tending to bring about relative axial movement therebetween. Stresses such as those, due to the quoins It which normally tend to separate the locking bars, are absorbed mainly by the undulations or teeth formed inthe locking bars themselves, and not by a locking collar or mechanism Which would be subject to mechanical failure. Thus the lock-up structure is much more durable than previous devices of the same nature. Additionally, because no bulky locking collar mechanism is needed at the intersection of the locking bars, the novel loch-up structure can be used to lock up larger printing forms than otherwise if a loc-king collar mechanism were required.

To prevent the interlocking bars from being separated by forces acting transversely to the longitudinal axes of the locking bars, safety loclring means are provided at the intersections of the bars. As is best shown in Figs. 5 through 7, the safety locking means comprises a mechanism including a base portion 26 slidably seated in the grooves 22 formed in each of the locking bars I3, anda locking latch portion 2l having a hooked end 28 co-operating with thev lip I9 formed in the undercut portions of th transversely extending teeth I8 on the outer sides of each of the locking bars I2. Base portion 26 and locking latch portion 2l of the mechanism are secured together by an operating handle portion 29 comprising a stem 3l threadably secured in base portionZ, and a handle receiving post 32 formed integrally with stem 3I and adapted to receive an operating handle. The base portion 26 of the safety locking means, when the operating handle portion 29 is loosened, can be set in any desired position along the length of the locking bars I3. Upon the locking bars being interlocked in a particular position, the safety locking'means is slid along the locking bar until it is in position adjacent the'intersection of the bar I3 with the bar I2. The latching portion 21 isfthen swung under lip I9, and the operating handle portion 2S then turned so as to draw latch'portion 27 up tightly against the side lof locking bar I3. This serves to rmly anchor the locking means in position relative to the locking bars, and to maintain the locking bars in assembled relatipn against the action of forces acting transversely to the longitudinal axes of the locking bar. Because of the simplicity of the construction of the safety locking' means, it can be appreciated that the construction of the lock-up device is not greatly complicated by its provision, but is greatly improved thereby due to the fact that in handling the lock-up structures having printed forms mounted therein, there ne'ed be no fear of the device coming apart due to forces that might easily separate the locking bars.

This greatly facilitates handling and storage of the structures after printing forms have been set therein.

Having set locking bars I2 and I3 in a desired position, mounted a printing form therein, and set the safety. locking means at the intersection of the locking bars, the printing form is then ready to be-locked or placed on a printing press. In the embodiment of the invention shown in Fig. 1 of the drawings, the lock-up structure is placed on the printing press by means of the piinters chase I8. To facilitate the placing or" the lock-up structure in the printers chase l S, movable means comprising end locking screws 33 are provided on the ends of each of the bars l2 and I3. The end locking screws 33 comprise bolts having nut-shaped heads adapted to fit against the sides of the chase I 'I which can be gripped with a wrench, and threaded stems 34 threadedly secured in the ends of each of the locking bars. When placing the lock-up structure Within the chase I l, the end screws 33 can be set in any desired position so as vto rigidly lock the lock-up structure within thechase. It should be noted, however, that practically no strain at all isimparted to the chase except that required to support the weight of the lock-up structure, the printing form, and the quoins I4. The stresses brought about by reason of the quoins I 4 are all absorbed by the interlocking teeth of the lockup structure, and need not be absorbed by locking collars, or other similar mechanism, which mightbe subject to failure under such stresses.

From Fig. 1 it is apparent that a considera-ble amount of space on any particular printing press .is taken up by the chase i? which might otherwise be used to accommodate larger sized printing forms if the chase were not needed. In order to'utilize this space, and do away with the need for printers chase, the'inve'ntion provides a lockup structure lthat can be placed on a printing press-with or without usinga chase. In order to accomplish thisfa pair of additional longitudinal bars 3l, onesof which iswshown in Fig.` are lockedon opposite sides oi the lock-upI structure which do not require the use of end bars. Each of the longitudinal bars 31' hasa` tapered portion 38 similar tothe tapered portion of the chase Il, and an overhangingl edge portion 39. which has a series of spaced, pedestal-like, rectangular shaped teethv 4l formed on its under surface inthe manner-.shown best in Fig. 9. The teeth 4|V are, in all respects, similar tothe teeth 2| on the locking bars l 3, and serve the same purposein thatv they mesh with the undulations in llocking bars I2 to rmlyv rinterloekthe additional longitudinal bars 3T with the ends of the locking bars l2' in substantially the' same manner as is shown in Fig. 4 of thel drawings. The overhanging edge portion ofthe additional end bars 31 also has a longitudinally extending groove llc formed .therein in which the base portion 26 of a safety locking means; identical in construction to the safety locking means illustrated inFigs. 5 through 7, is mounted. Upon the additional end bars being secured tothe lock-up structure, the structure may be flocked. on a printing press without the use of` a printers chase,l thereby allowing the space otherwise taken up by the chase to be used to accommodate a larger'printing form Il.

While the invention. has been described in connection with. a printingv `type lock-up structure, it iscOntempIated that the invention be used in locking-up foundry forms, in which the locking structure, or to be exactthe portion of the locking structure surrounding the printing form would beso designed as. to extend a height level with the height of the type. Further,`the novel lock-up structure maybe used as a page tie-up device in placel of string or other presently used means for tieing-up pages Loitype or printing forms afterthey have been made up', and before they are to be placed on a press. Consequently, the storage and handling of made up pages of type-and-printingforms is greatly facilitated by the invention.v

Anfurther intended use of theV novel lock-up structure isv inv connection with the making-up of printing forms wherein the structure may` be adapted for use asa galley having removable, reversible ends. By reversing the ends oiga galley, thus: constructed, the handling of' type as it comes off the type setting machine is greatly facilitated. Also: while the disclosed form of the undirlations4 in the locking bars is particularly adventagecus, it is to be understood .that the invention is not to be restricted to the exact design disclosed but that the undulations may be shaped in any desired manner, the only requirement being that they cooperate to `rrnly interlock the locking bars of the locking device against vrelative axial movement. If desired, the teeth may be formed ati some angle other than right angles so that the device can be used to mount printing forms set' at an angle.

From the foregoing description it can be appreciated that the invention provides a novel printing type lock-up structure which facilitates thelocking up of printing type forms on a printing' press' in that it does not require the use' of printersfurniture, or other spacing-out devices such-as the cross bars used on cylinder chases. Theloek-up structure can be easilyadjusted and aligned to accommodate any desired size printing formy with a. minimum of effort, and without.v requiring time consuming adjustmentof a complicated locking collar, or the like. Because of the manner in which the component partsI thereforinterlock, the possibility of.mechancal failure of the structure -is reducedfto'a minimum and the structure is capable of accommodating larger printing forms.. TheV device can be easily adapted to accommodate eveny larger sized printing forms than could otherwise be used on a particular size pressby the simple provision of a pair of additional longitudinal bars, and: can be easily designedto provide for the mounting vof printing forms on an angle. Thus, theV invention provides a novelprinting type lock-up-structure incorporating many desirable features- Having thus described my invention, it is obvious that various immaterial modications may be made in the samer without departing from the spi-rit of'myinvention; hence, I do not wish. to beunderstood as limiting. myself to the exact form, construction, arrangement, and combination: of rparts herein shown and described,v or uses mentioned.
